THE ULTIMATE TRAIL BIKE
The Stumpjumper ST models are snappy and nimble, yet Incredibly versatile—the perfect rigs for riders seeking both efficiency and capability. The Stumpjumper ST Alloy 27.5 makes that winning combo affordable, with components that are big on performance and small on dollar signs.
The innovative sidearm frame design makes a lighter, better-handling bike. By directly connecting all three mounting points of the rear-end and shock to the frame, we've increased both stiffness and performance over bumps. End result? Total control.
Our in-house suspension-tuning team develops custom shock tunes, perfectly paired to each bike's kinematics. We call this Rx Tune and while it's not the easy way to build a suspension bike, it's worth it. You feel Rx Tune as perfectly-balanced suspension.
SMART PARTS PICK

• 130-millimeters of suspension courtesy of a RockShox Recon RL fork.
